From 3d49ee8510d38e7fd087c7250a3f4392a38bf0dd Mon Sep 17 00:00:00 2001 From: Masahisa Kojima Date: Tue, 26 Oct 2021 17:27:24 +0900 Subject: efi_loader: add SMBIOS table measurement TCG PC Client Platform Firmware Profile Specification requires to measure the SMBIOS table that contains static configuration information (e.g. Platform Manufacturer Enterprise Number assigned by IANA, platform model number, Vendor and Device IDs for each SMBIOS table). The device- and environment-dependent information such as serial number is cleared to zero or space character for the measurement. Existing smbios_string() function returns pointer to the string with const qualifier, but exisintg use case is updating version string and const qualifier must be removed. This commit removes const qualifier from smbios_string() return value and reuses to clear the strings for the measurement. This commit also fixes the following compiler warning: lib/smbios-parser.c:59:39: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] const struct smbios_header *header = (struct smbios_header *)entry->struct_table_address; Signed-off-by: Masahisa Kojima --- lib/efi_loader/efi_boottime.c | 2 ++ 1 file changed, 2 insertions(+) (limited to 'lib/efi_loader/efi_boottime.c') diff --git a/lib/efi_loader/efi_boottime.c b/lib/efi_loader/efi_boottime.c index 352c2db25a..973134b12d 100644 --- a/lib/efi_loader/efi_boottime.c +++ b/lib/efi_loader/efi_boottime.c @@ -86,6 +86,8 @@ const efi_guid_t efi_guid_event_group_reset_system = /* GUIDs of the Load File and Load File2 protocols */ const efi_guid_t efi_guid_load_file_protocol = EFI_LOAD_FILE_PROTOCOL_GUID; const efi_guid_t efi_guid_load_file2_protocol = EFI_LOAD_FILE2_PROTOCOL_GUID; +/* GUID of the SMBIOS table */ +const efi_guid_t smbios_guid = SMBIOS_TABLE_GUID; static efi_status_t EFIAPI efi_disconnect_controller( efi_handle_t controller_handle, -- cgit v1.2.3
